SPECIFICATION forming part of Letters Patent No. 655,354, dated August'7, 1900.

Application filed October 20, 1891. Serial No. 409,341. (No model.)

To all whom it may concern.-

Beit known that I, WALTER SCOTT, a citizen of the United States, and aresident of Plainfield, in the county of Union and State of New Jersey,have invented certain new and useful Improvements in Printing-Machines,of which the following is a specification.

The present invention relates to web-perfooting presses, and moreespecially to mechanism for causing register of the webs from aplurality of presses, the principal objects of the invention being tosecure ready and accu rate compensation for faulty registry of theprinted matter on the webs and also to permit of the slacking up of thewebs between the printing-press and the folding mechanism in case suchslacking up should be required or necessary and the restoration of thewebs to the exact registry whenever the slack is taken up again.

To these and other ends the invention includes features of constructionand combinations of devices hereinafter described, and more particularlypointed out in the appended claims.

The preferred form of the invention is illustrated in the accompanyingdrawings, forming part of this specification, in which-- Figure 1 is adiagrammatic side elevation of the press. Figs. 2, 3, and 4 are detailviews. Fig. 5 is a diagrammatic view of a modification. Figs. 6 and 7illustrate the placing of sheets, and Fig. 8 associating bars.

Three presses are shown arranged one above another, the web P for theupper press leading about rolls 10, 11, and 12 in itsway to and from thesaid upper press, the web Q leading about rolls 10 11 as it passes fromand to its press, and the web It leading about rolls 10 116, and 12 asit moves to and from its press. The web is supported between the rolls11 and 12 by tapes 13,'which run upon rolls or pulleys 14 15. The web Qis supported after it leaves the roll 11 by tapes 19, which run uponrolls 18 and 20. v The web It is supported between the rolls 116 and 12by tapes 22, running upon rolls or pulleys 23, 24, and r. The web 4'passes from the roll 12 between cutting-oylinders 25 26 of a sizeadapted to cut half-length sheets from the said web, and saidhalf-length sheets are carried out upon tapes 27, running upon rollers28 29 and an adj ustable roll 30. Fixed guides 31 32 above and below thetapes 27 prevent the sheets from rising therefrom. The roll 30 is carried by adjustable arms 33. The half-sheets from the web R are run bythe tapes 27 between cutting and folding cylinders 74 75 and are thereassociated with the webs P Q. The cylinders 74 75 are provided withcuttingblades 76 and grooves 77 for severing full length sheets from thewebs P Q. The cylinder 74 is provided with a tucking-blade 78, and thecylinder 75 is provided with groove 81 for coaction with saidtucking-blade and with sheet 82 for nipping the creased sheets, saidtucking-blade and groove 81 being opposite the cutting devices of thesaid cylinders 74 7 5. The sheets cut by the cylinders 25 26 are halfthe length of the sheets cut by the cylinders 74 75 when the lower pressis running at half the speed of the two upper presses, and thehalf-sheets may be associated with the full length sheets in the mannerindicated in Fig. 6 or in that indicated in Fig. 7. In both Figs. 6 and7, m m indicate outer margins of the print, and c 0 indicate innermargins of the print, while 1, 2, and 3 indicate the sheets cut from thewebs A Q B, respectively. In both figures, 109 indicates the line offold by the tucking-blade 78 and groove 81, and 112 113 represent theedges cut by the blade 76 and groove 77. The cylinders 25 may be sotimed as to secure that the front margin of the sheet 3 shall overlapthe crease at 109, as indicated at 110 in Fig. 6 or as indicated at 111in Fig. 7. The grippers 82 carry the sheets around until the time thetucker-blade 8O coacts with the groove 84 and grippers 85, but fold thesheets again transversely and to transfer them to the cylinder 83,whence they are delivered between the cylinder 83 and roller 86 upontapes 87, which run about the cylinder 83 and rolls 86 88 and pass to afolder M, whence they are delivered.

The web P passes about rollers 41, 42, and 16 and to the cylinder 75,and the web Q passes about roller 18 directly to said cylinder 75. Therolls 41 42 are carried, respectively, by arms 43 4.4,which project froma'rock-shaft 45, journaled in'the framework of the machine, the arms 4344 being so placed that the web in passing from the upper side of rolldriving the latter.

41 to the under side of roll 42 does not touch the shaft. The shaft 45is provided with an arm 46, which is adjusted as hereinafter described.Paste is applied to the web P by a revolving blade 17, carried in armsfrom a rotating shaft 47 and taking paste from a roller 48, runningin apaste-fountain 49. The shaft 47 has a gear 50 thereon,which meshes withthe gear 51 to drive the fountain-roller 48. The shaft 47 also has agear-58 thereon, which meshes with the gear 57 to a train of gearing 576O 61 62, coming from the middle press. A gear 59 on a shaft 54 mesheswith the gear 57 to rotate the shaft 54. Paste is applied to the web Q,by a revolving blade 21, carried in arms from the shaft 54. The shaft 54has a gear 55 thereon,which meshes with a gear 56 on the shaft of thefountainrcller 52, which runs in a paste-fountain 53, the blade 21taking paste from the roller 52. A gear 90 connects the gear 57 with thecylinder 55, and a gear 91 connects the cylinder 74 with the pulley 29for running the tapes 27.

91 indicates a driving-pulley intermediate the cylinder 26 and thetape-pulleys 24 for The cylinder 26 is driven by atrain of gearing 93 94from the lower press.

92 indicates the folding and cutting apparatus of the cylinders 25 26.

For the purpose of driving the lower press at the same speed as or athalf the speed of the two upper presses the shaft 35 of the secondimpression-cylinder of the lower press has two gears 36 37 fast thereon,and a shaft D is provided with adjustable gears 38 39, which are heldfrom rotating independently of the shaft 1) by means of a feather andgroove or by means of a groove and set-bolt 40.

34 is a gear intermediate the upper and middle presses.

The roller 18 is carried by arms 63 from a rock-shaft 64, and the shaft64 has an arm 65, preferably of resilient material.

66 indicates a toothed catch bar or arm which is journaled at 67 to anarm 73 in the fixed framework of the machine. The arm 66 is providedwith lugs 71 72 at opposite sides of the arm 73, and the lugs 71 72 areprovided with adjusting clamping-screws 69 7 O for coaction with theopposite sides of the arm 73, whereby the arm 66 may be swung about itspivot 77 to move atooth 68 thereof into various positions. The arm isdrawn upwardly by the tension of the web Q on the roller 18, and itsupward motion is arrested by the tooth 68 on the arm 66. By springingout the arm 65 it maybe disengaged from the tooth 68 and the roller 18may be lowered to slack up the web Q. Upon returning the arm 65 intoengagement with the tooth 68 the web Q is brought back to its properposition and the registry thereof with the webs P R is not disturbed.The arm 46, above named, may be held in position by identical means andbe operated to slack up the web P at the take-up U and be returned toengagement with its catch, thus restoring the registry of .the web P.Some of the advantages of this construction of the take-ups are that thetake-up permits of ready and accurate compensation for faulty registryof the printed matter on the webs by proper manipulation of the screws69 70; also, as above stated, after proper registry has been secured thearm controlling the take-up and let-off may be moved away from the catchtherefor and be sprung outward and be moved above the tooth 68 for anypurpose, and thereafter be returned to its position under said toothwithout in any wise disturbing the registry.

The printing-presses imprint double-width webs, and the sections of theweb, as P P may be associated with each other by means of parallelturning bars 114 115, as indicated in Fig. 8.

When the lowest press is run at the same speed as the upper presses, theweb R is taken around a roller 117 and not between cuttingcylinders 2526 on its way to the cylinder 74 75.

The blade may be fixed to the cylinder 75, and the cylinder 76 may havea flattened portion 79 to permit the blade 80 to pass thereby. In thiscase the blade 76 may only perforate the paper and the blade 80 serve totear the sheets from the web at the line of perforation. I

In the modification illustrated at Fig. 5 the cylinders 74 7 5 havetheir positions inverted and the cylinder 74 is provided with acutting-blade 7 6 and with a creasing-blade 78 and with pins 96, whilethe cylinder 75 has cutting-groove 77 and a tucking-groove 81 andgrippers 82. The cylinder 75 is grooved at 97 to receive thestripping-guides 98, and the sheets are delivered from the cylinder 75between said guides 98 and tapes 108, running upon rollers 107. Thecylinders 25 26 are arranged to sever half-length sheets from the web R,92 indicating the cutting-blade, and the corresponding groove in thecylinder 26*. cylinder 26 which is grooved at 105 to receive strippers104, between which strippers and guides 103 the sheets are carried outonto the tapes 27, which run upon pulleys 28 29. 99 is a set of tapesrunning upon rollers 100 101 above the tapes 27. 106 indicates guideswhich support the sheet between the pulleys 29 and the cylinder 75. 102indicates a gear intermediate the cylinder 26 and the pulleys 100. 7

By leading the web P from the second impression-cylinder of the upperpress to the first impression-cylinder of the middle press, as indicatedby the line X, and from the second impression-cylinder of the middlepress to the first impression-cylinder of the lower press, as indicatedby the line Z, a plurality of impressions upon each side thereof may besecured.

What 1 claim is 1. The combination with a rock-shaft, a take-up borne byarms thereon, and a lever a indicates pins in the.

thereon to operate the same, of an adjustable toothed holder on theframe for said lever, and screws acting on said holder to move the samefor adjustment, whereby the take-up can be accurately adjusted toposition, and then be moved out of and into position at will,substantially as described.

2. The combination of a number of printing-presses arranged one overanother and each perfecting its own web, a folding and cutting mechanismto which all the Webs are taken, web take-up or register roll or rollsfor one or more of said webs, a rock-shaft and arms therefrom for eachtakenp for carrying said rolls, a resilient or flexible arm on eachrock-shaft, and a stop for each of the lastnained arms for limiting themotion thereof in one direction and from which said arm may be freed bybeing flexed or sprung and so be moved freely to slack up thecorresponding web and be returned to position without disturbing theregister of the webs, substantially as described.
